I want to scramble a m*n size gray scale image.I just want to make a great disturbance between the pixels so that the image can be completely distorted.For this I need a code for this and I am a beginner and using R2010a version. I have done a code like this but its not efficient. It does not scramble the image completely. grayImage = imread(); subplot(1,2,1); imshow(grayImage); [rows, columns, numberOfColorChannels] = size(grayImage); N=rows; T=1.4938*N+40.8689; disp(T); t=0; T2=ceil(T); disp(T2); c = T imscram= grayImage; while t<T2 for i= 1 : columns for j= 1 : rows r = mod(i+j,N)+1; c = mod(i+(2*j)+1,N)+1; imscram(i,j)=imscram(r,c); end end end
t=t+1; fprintf('t = %f, T2 = %f\n', t, T2); subplot(1,2,2); imshow(imscram);

Shivani, did you overlook the attached file? It's below the image and called scramble_image.m.
